george. We sure do, josh. And joining us now is nev schulman. Also, our "gma" legal analyst, dan abrams. Nev, let me begin with you. Maybe this is a generational thing. I look at the facts. A relationship going on several months. They never meet. I say, there's no way this is true. But you believe him. Yeah. I stand by the guy. My heart goes out to him. I feel like he's dealing with more emotionallyha tn anyone's giving him credit for. His heart was broken. He's grieving, a girl whether she existed or not, those are real feelings. Your brother says he was the victim of a hoax like this. What were you able to discover in this story? My brother's been deep in it with his co-host, max joseph. And they uncovered a few other people that were duped by the fake lennay character. Sort of like my brother's story, it's bigger than just manti. There were other people she was corresponding with, before and maybe even during her relationship. You went and looked at the interviews, how long was it able to go on so long without being uncovered? When you want something bad enough, in his case, a connection with someone, you're willing to ignore a lot of red flags and create a scenario that allows you to continue believing. Same thing with my brother. He wanted this girl to be real. He wanted the love to be real. And he ignored everything else. The hardest thing for people to accept, is even after he knew, lennay was alive, he continued to at least not reveal that fact. I know your brother's reached out to him. Have you heard anything about that at all? No. I think nev has said manti, i know what you went through. The exact same thing happened to me. I don't think manti is reaching back at the moment. Maybe he will. And, dan, are there any laws broken here in any way? It depends. You know, look. It depends what state it occurred in. Let's assume that it occurred in a state where it's against the law to take someone's identity and lie about it. You had to have done it with the intent harm, intimidate, threaten, et cetera. And here, there are -- isn't that implied by trying to fool someone in that way. The definition of harm comes in. You're allowed to create a parody account. I can take george stephanopoulos and put a picture and make fun of george stephanopoulos. Please don't. And that's okay. That's perfectly legal. But if you do it with the intent to create harm, et cetera. We don't know if -- we don't know exactly what's happened here. On the flip side of that, some people are asking, what about him? What if he made this up? Could he face any legal problems? And the answer to that one is no. How about notre dame? Notre dame knew the truth and didn't reveal it, either. First of all, he's under no -- let's assume he knew this was a hoax. He's allowed to lie to the public. Allowed to lie to the media. He's not allowed to lie to the authorities. Notre dame had no obligation to come forward. The media says, we're entitled to know everything that is true. Yeah. It's irritating. It's deceptive sometimes. But it doesn't mean that there are legal issues associated with it. The more likely scenario would be, if someone's likeness is taken, that person ends up suing and saying, wait a second. You took my likeness for this purpose, particularly for financial gain, and I'm going to sue you. We don't know the facts here well enough to know what sort of potential legal issues. We covered so many cases like this. What's your gut on how it ends? My gut is that there's a -- i guess a lonely person behind it all, that didn't expect it to this far. And was looking to connect with someone. And that someone was manti because he was looking for the same connection. And we'll find that there was no malicious intent initially. And it just started off as two people looking for love. That happens. That will -- this will go down as one of the most amazing stories. It sure will. We're all going to find out, we hope, one day. Let's get the weather from
